"First it was coconut milk, then coconut water, and now coconut oil — and I think a big part of the recent popularity is that it's natural, not synthetic, which is so appealing," says Francesca Fusco, MD, a dermatologist at Wexler Dermatology. Coconut oil, unlike mineral oil, delivers on the same skin softening but possibly more effectively. "Research has shown that from the use of coconut oil on skin, hydration improved and skin surface lipids remained in tact," she says. And when it comes to "thick, scaly, fissured feet, or rough leathery elbows and knees, coconut oil might have the advantage over regular moisturizer."

2. Clears up skin conditions

And, it could also be the answer to chronic skin conditions such as eczema, too. "Coconut oil is an excellent moisturizer and a good anti-inflammatory, so its use for eczema is on the rise," says Ted Lain, MD, a dermatologist in Austin, Texas. "We know that it has inherent moisturizing properties just from its oily consistency, and that the anti-inflammatory effects are likely related to antioxidants such as polyphenols." Lain points out a recent double-blinded study comparing mineral oil to coconut oil as topical treatment for children with eczema. "It showed that 46% of patients using the coconut oil had an excellent response as compared to only 19% of patients using only mineral oil."

3. Reduces inflammation

"The combination of anti-inflammatory, antioxidant, anti-bacterial, and hydrating properties make it truly unique," says Whitney P. Bowe, MD, a dermatologist at Advanced Dermatology PC. "Coconut oil is primarily composed of saturated fats and contains medium-chain fatty acids, which not only help to repair the skin barrier and trap water, thus hydrating the skin, they also reduce inflammation." Bowe suggests gently rubbing a few drops of the oil into the skin around the eyes nightly using your fingertips, but rubbing a more generous amount onto legs, elbows, knees, and heels "to help smooth the skin and trap moisture."

4. Strengthens hair

The benefits of coconut oil don't stop at the skin, says Fusco. "The real benefit is with scalp and hair application," she says. In one study, coconut oil reduced protein loss in both damaged — and undamaged — hair when used before shampooing and as a leave-in treatment. "Coconut oil is able to penetrate the hair shaft due to its low molecular weight and affinity for proteins," says Fusco. There are tons of real life testimonials that say slathering the real deal on strands and skin are all a part of a daily beauty routine. Smoother hair. More shine. Not to mention crazy soft skin.

When to avoid it:

But not everyone should apply it head-to-toe, such as those prone to breakouts and who have very oily skin. Fusco suggests dropping some into your go-to face cream to take the hydration factor up a notch without going oil overboard. And Lain agrees: "I feel comfortable recommending this as a daily moisturizer to patients for their face and body," says Lain. "My only reservation is for people with acne-prone skin, as it may be comedogenic. However, the anti-inflammatory and anti-aging benefits of the polyphenols also make coconut oil part of a rejuvenating skincare regimen."

The other undeniable pro? The smell. "Coconut oil has an appealing aroma too," says Fusco. "It reminds us of summer, vacation and pina coladas."
